    Abstract: To provide a solid catalyst component for olefin polymerization having a small amount of fine powder. A solid catalyst component for olefin polymerization containing a titanium atom, a magnesium atom, a halogen atom, and an internal electron donor. The solid catalyst component has an absolute difference in binding energy of 73.50 to 75.35 eV between a peak (1) with the binding energy of 457.00 to 459.00 eV and a peak (2) with the binding energy of 532.50 to 534.50 eV. The peak (1) and the peak (2) are within peak components measured by X-ray photoelectron spectroscopy, the peak (1) is obtained by waveform separation of peaks assigned to the 2p orbitals of the titanium atom, and the peak (2) is obtained by waveform separation of peaks assigned to the is orbital of an oxygen atom.

    Abstract: The present disclosure generally relates to alkylated aromatic compounds useful as basestocks and additives for high viscosity applications. In an embodiment is provided an alkylated aromatic compound. In another embodiment is provided a lubricant formulation that includes an alkylated aromatic compound. In another embodiment is provided a lubricant formulation that includes an alkylated aromatic compound, an additive, and optionally, a Group III basestock, Group IV basestock, Group V basestock, or a combination thereof, the Group V basestock being different than the alkylated aromatic compound. In another embodiment is provided a method of forming a lubricant formulation that includes introducing a mPAO, an aromatic compound, and an acid catalyst to a reactor under reactor conditions to form an alkylated aromatic compound; and introducing the alkylated aromatic compound to an additive to form a lubricant formulation.

    Abstract: A method of operating a dump tank of a polymer production process by transferring all or a portion of a content of a polymerization reactor into the dump tank, wherein the reactor contents comprise solid polymer, and liquid and gaseous non-product components, and removing at least a portion of the liquid and gaseous non-product components from the dump tank by: reducing a pressure of the dump tank, subjecting the solid polymer to a first cleaning stage comprising heating the solid polymer by introducing a first heated treatment gas into the dump tank, and subjecting the solid polymer to a second cleaning stage comprising purging the solid polymer by introducing a second heated treatment gas into the dump tank.

    Abstract: Vanadium phosphinic complex having general formula (I) or (II): V(X)3[P(R1)n(R2)3-n]2  (I) V(X)3[(R3)2P(R4)P(R3)2]  (II) wherein: X represents an anion selected from halogens; or is selected from the following groups: thiocyanate, isocyanate, sulfate, acid sulfate, phosphate, acid phosphate, carboxylate, dicarboxylate; R1, identical or different among them, represent a hydrogen atom, or an allyl group (CH2═CH—CH2—); or are selected from alkyl groups C1-C20, linear or branched, optionally halogenated, optionally substituted cycloalkyl groups; n is an integer ranging from 0 to 3; R2, identical or different among them, are selected from optionally substituted aryl groups; R3, identical or different among them, represent a hydrogen atom, or an allyl group (CH2═CH—CH2—); or are selected from alkyl groups C1-C20, linear or branched, optionally halogenated, optionally substituted cycloalkyl groups, optionally substituted aryl groups; R4 represents a group —NR5 wherein R5 represents a hydrogen atom, or is selected from C1-C20 alkyl groups, linear or branched; or R4 represents an alkylene group —(CH2)p- wherein p represents an integer ranging from 1 to 5; provided that in the general formula (I), in case n is equal to 1 and R1 is methyl, R2 is different from phenyl. Said phosphinic vanadium complex having general formula (I) or (II) can be advantageously used in a catalytic system for the (co)polymerization of conjugated dienes.
